Scaling Pictures to Safe Zone

Is there a way to globally scale all the slides in the show to fit the safe zone at one time, with no pan or zoom. I can find how to adjust them individually, but would like to select slides and scale to fit in one operation. Going through all them one by one is painful.

Anyone??

Not as far as I know…

Appreciate the response

You can copy and paste the geometry of a slide via a right/alternative click in the stage area, maybe that helps?
